摘要
网纹绵蚧Chloropulvinaria polygonata(Cockerell)是为害柑桔的重要害虫之一,寄主广,年发生二至三代,以二代为主,世代重叠。平均产卵量,第一代为1006.5粒,越冬代为1450.86粒。在适宜生境内的空间格局,越冬代或第一代发生密度较低时,多表现为奈曼A型分布;猖獗发生年的第一代主要表现为负二项分布。保护利用自然天敌是综合治理该虫的关键措施。
Chloropulvinaria polygonaia (Cockerell) is one of the most important pests in citrus cultivation in Sichuan Province. It infests a wide range of host plants and breeds two to three overlapping generations annually. The overwintering generation has a higher fecundity than the first generation and the average numbers of eggs laid per female are 1450 and 1007 respectively. When the population density is low under suitable environmental condition, this scale shows Neyman type A distribution, but the first generation of rampant year shows negative binomial distribution. For its effective integrated mana ement preservation and utilization of natural enemies are emphasized.
